Abstract
A toner cartridge for use in replenishing additional toner to a toner storing section of an imaging machine, such as an electrophotographic copier, which uses toner to produce a visible image is provided. The present toner cartridge includes a trough-shaped container having an opening, a cover which is large enough to encompass the opening and supported to be slidably movable with respect to the container between a closed position to close the opening and an open position to open the opening, and a seal member having one end fixed to the container and another end fixed to the cover. Thus, when the cover is moved from the closed position to the open position, the seal member is partly separated away from the container to make the opening half-open. Then, the seal member is pulled to completely open the opening to have the toner completely discharged from the container. Thereafter, the cover is returned to the closed position to close the opening. With such a structure, toner is completely prevented from being scattered.
